I actually would rather keep it as is. To be completely honest the powercreep in skill every expac makes these dungeons go by much much quicker, and the fact tanks now have aoe at low levels speeds up the process drastically.

I'd also rather keep the fights as they are, as many people are going into XIV for the first time or are learning a new job, so the options to wall to wall for experienced players or have them learn their job like normal are both options you can do.

Also keep in mind that they serve as a time capsule for how those fights used to be in the ye olden days. When I look at a dungeon like Copperbell Mines and compare it to Malikah's Well it's insane how far we've come.
